CWWIM4551E Change handler was not defined for repository type 'DOMINO'

After changing the LDAP Server for my Sametime Cell, I was unable to start a Websphere Server using the nodeagent.

On the SystemOut.log for the nodeagent I saw the following messages:

[8/27/14 11:51:05:381 BRT] 0000003d exception     E com.ibm.ws.wim.adapter.ldap.change.ChangeHandlerFactory getChangeHandler CWWIM4551E  Change handler was not defined for repository type 'DOMINO'

Stopping the nodeagent did not work:

           because of insufficient or empty credentials.

           running tool from the command line, pass in the correct -username

I had to kill -9 the nodeagent process, and then manually sync the node with the System Console:

/opt/IBM/WebSphere/AppServer/profiles/STMSPNProfile1/bin # ./syncNode.sh stsc.company.com 8703 -username wasadmin -password P@ssw0rd
